General Mach Discussion / Loud noise from steppers and machine
« on: April 07, 2018, 12:59:00 PM »
I'll add a video with sound. Had to replace controller board with a later board (TB6600- 4 AXIS Ver 2.0) as original board died about two years ago.  Couldn't get the new board to cut right, it was cutting four times too big.  Let it sit for a while to do other things and now I'm back to trying to make it work again.  Fixed the cutting four times too big problem by doing an axis calibration.  Cuts correctly now along x,y and z axis but makes horrible noise as it cuts something from G Code.  Runs very quietly as it is being jogged. Believe my problem is in configuration files, although I didn't change anything when I changed over to the new controller.  Does anyone have any suggestions?

General Mach Discussion / General Logic Configuration- Tool Change
« on: December 26, 2014, 10:01:52 AM »
Stop Spindle Wait For Start-  I have been cutting with Mach lll for a year or so and have never needed to change tools.  Now I need to change multiple times.  I have ordered a MuscleChuck.  I do not have a automatic tool changer and will change tools manually.  Under General Logic Configuration I want to select stop spindle wait for start.  I know that stops the spindle and then waits for me to tell the system to start again after I change the tool.  Since all of my work is flat panel I don't have home switches.  I just manually zero the machine.  I am using VCarve Pro and will set my post processor to General ATC or Mach lll ATC so the tool changes will be in the g code for Mach lll to recognize.  Two main questions, when the spindle stops how do I make it go somewhere safe and convenient to change the tool (I have never written any g code), and then how to I re-zero the tool.

I know every question is answered here somewhere.  I just couldn't find it.  Thank you.

General Mach Discussion / Drill Mill Hole Primer- Suggestions?
« on: November 15, 2013, 08:58:00 PM »
Can anyone point me towards the best info in the videos or manuals on how to drill some 1/8" x 1 1/8" holes in MDF. My router is cutting outside the hole.

Thanks, I searched here and Mach 3 on Yahoo but couldn't come up with anything.

General Mach Discussion / Machine Zero
« on: November 10, 2013, 08:18:57 PM »
I've read a lot threads on machine zero.  I still can't get my machine to do what I want.  I have a 4 x 8 table and only cut sheets of ply.  I zero my table at the corner of the sheet and the dxf/gcode origin.  No problem there.  Go to zero takes me to zero every time.  However it now wants to load my gcode at the MACHINE ZERO.  Thinking maybe I have a setting wrong.  What I need to know is if I can zero machine coordinates to table/work coordinates without home/limit switches and if so how.

Thanks, Joe
